         8 . The communication system according to one of claims  5  and  6 , wherein the sixth means reproduces the voice data concurrently with the voice data storage in the fifth means.  
     
     
         9 . A communication terminal comprising: 
 a first means for recording voice data;    a second means for generating data A containing the recorded voice data and a control signal commanding the storage and reproduction of the voice data with respect to other communication terminals; and    a third means for transmitting the data A to the other communication terminals.    
     
     
         10 . A communication terminal comprising: 
 a fourth means for receiving data A including recorded voice data and a control signal for controlling the operation of the communication terminal from the other communication terminals;    a fifth means for storing the voice data contained in the data A on the basis of the control signal contained therein; and    a sixth means for reproducing the voice data contained in the data A on the basis of the control signal contained therein.    
     
     
         11 . The communication terminal according to  claim 10 , wherein the sixth means reproduces the voice data stored in the fifth means.  
     
     
         12 . The communication terminal according to  claim 10 , wherein the fifth means reproduces the voice data concurrently with the voice data storage in the fifth means.  
     
     
         13 . The communication terminal according to one of  claims 9  to  12 , which is a mobile communication terminal.  
     
     
         14 . A communication system for transmitting voice data from a first communication terminal to a second communication terminal, wherein 
 the first communication terminal performs the following steps of: 
 a first step for storing an input voice data in a first memory in an voice data input mode settable by a user's operation;  
 a second step for selecting a usual communication mode or a voice data transmission mode; and  
 a third step for performing the usual communication when the usual communication mode is selected and transmitting the voice data and a specified data indicating the selection of the voice data transmission mode, and then disconnecting a line.  
   
     
     
         15 . The communication system according to  claim 14 , wherein the first communication terminal further performs a fourth step for checking whether the voice data have been completely transmitted, and re-transmitting the voice data after re-connecting the line when the voice data have not been completely transmitted.  
     
     
         16 . The communication system according to  claim 14 , wherein the first communication terminal further performs a fifth step for ending the voice data transmission when the communication zone is not covered or when the second communication terminal is rejecting the call reception.
